Abstract :
A Dynamic Spectrum Management (DSM) Wi-Fi Prototype Platform is described in this paper. The platform hosts a modified 802.11n waveform that operates in TV White Space (TVWS), receives channel lists from a TVWS database, evaluates channel quality, and selects and aggregates data transmitted across up to four noncontiguous channels. The over-the-air (OTA) performance results collected in the Melville, New York lab are described. The results include data throughput, received signal strength indicator (RSSI), interference sensing and signal-to-noise plus interference (SNIR). The results are analyzed, including the advantages and efficiency of channel aggregation; indicate issues that were uncovered during testing and present possible solutions.
